Lithium Phosphate, low form (iithiophosphate), Li3PO4 (orthorhombic)Powder data cards The dengity of lithium phosphate, low form,calculated from the NBS lattice constants is 2.480g/cm3 at 25 °C.Cardnumber12-230Indexlines3.983. 802.67Fisher [1] 1958.SourceA high form is obtained from samples that havebeen heated above approximately 500 °C.Additional published pattern. Matias and Bondareva[2] 1957.NBS sample. The sample of lithium phosphatewas obtained from the City Chemical Co., NewYork, N.Y. Spectrographic analysis showed thefollowing major impurities: 0.1 to 1.0 percent calcium; 0.01 to 0.1 percent each of aluminum, sodium, and strontium; and 0.001 to 0.01 percenteach of barium, iron, magnesium, and silicon.The sample was colorless. The indices of refraction could not be determined because thesample was too fine.The d-values of the three strongest lines are:3.973, 3.797, and 2.640 A.Structural data. Zemann [3] in 1960 studied acrystal of Li3PO4 that had been grown in moltenLiCl and determined that it has the space groupD^-Pmnb (No. 62) and 4(Li3PO4 ) per unit cell.We find that the lower form apparently has thesame structure with only slight changes in thelattice constants, principally in the c-direction.The cell constants of Zambonini and Laves havebeen converted from kX to angstrom units forcomparison with the NBS values.19321963Zambonini andLaves [4],National Bureauof Standardsat 25 °C.Lattice constantsaA6.086. 1155± . 00046A10. 2810. 467±.001cA4. 874. 8452± . 0005References[1] D.

Lithium Phosphate, high form, Li3PO4 (orthorhombic)Powder data cards. None. Powder data cardNo. 12-230 has a pattern by Fisher [1] which seemsto be for the low form. The sample is changedto the high form when it has been heated aboveapproximately 500 °C.Additional published patterns. Tien and Hummel [2J, 1961.NBS sample* The sample of lithium phosphatewas obtained from the City Chemical Co, NewYork, N.Y.
